Thomas Mueller commented on JCR-3652:
-------------------------------------
I think I have a test case now that can reproduce the problem with very simple
operations (only one workspace):
{code}
public void testCopyCheckedOut() throws Exception {
Node root = superuser.getRootNode();
String nodeName = "testCopyCheckedOut" + System.currentTimeMillis();
if (root.hasNode(nodeName)) {
root.getNode(nodeName).remove();
superuser.save();
}
Node test = root.addNode(nodeName);
Node a = test.addNode("a");
Node b = test.addNode("b");
b.addMixin("mix:versionable");
superuser.save();
Value v = b.getProperty("jcr:isCheckedOut").getValue();
try {
a.setProperty("jcr:isCheckedOut", v);
} catch (ArrayIndexOutOfBoundsException e) {
System.out.println("set failed strangely: " + e);
}
System.out.println(a.getProperty("jcr:isCheckedOut").getValue().getString());
System.out.println(b.getProperty("jcr:isCheckedOut").getValue().getString());
}
{code}
This test prints "set failed strangely:
java.lang.ArrayIndexOutOfBoundsException: 0" and then fails with
{code}
javax.jcr.RepositoryException: property
/testCopyCheckedOut1377674810028/a/jcr:isCheckedOut: single-valued property
with no value
at
org.apache.jackrabbit.core.PropertyImpl.internalGetValue(PropertyImpl.java:492)
at
org.apache.jackrabbit.core.PropertyImpl.getValue(PropertyImpl.java:510)
{code}
This is with my current version of Jackrabbit (that has added checks)
> Bundle serialization broken
> ---------------------------
>
> Key: JCR-3652
> URL: https://issues.apache.org/jira/browse/JCR-3652
> Project: Jackrabbit Content Repository
> Issue Type: New Feature
> Components: jackrabbit-core
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Minor
> Fix For: 2.4.4, 2.7.1
>
> Attachments: JCR-3652.patch, JCR-3652-test-case.patch
>
>
> I have got a strange case where some node bundle is broken, seemingly because
> a byte is missing. I can't explain the missing byte, but it is reproducible,
> meaning that writing the bundles again will break them again. There are 11
> broken bundles, 10 of them have the size 480 bytes and one is slightly
> larger. It is always a boolean property value that is missing, always the
> value for the property jcr:isCheckedOut.
> As a (temporary) solution, and to help analyze what the problem might be, I
> will create a patch that does the following:
> * When serializing a bundle, check if the byte array can be de-serialized. If
> not, then try again. Starting with the 3th try, use a slower variant where
> before and after writing the boolean value the buffer is flushed. I'm aware
> that ByteArrayOutputStream.flush doesn't do much, but maybe it solves the
> problem (let's see) if the problem is related to a JVM issue.
> * If de-serializing a bundle fails, check if it's because of a missing
> boolean property value. If yes, insert the missing byte.
> I have also added some log messages (warning / error) to help analyze the
> problem.
